New study shows women's size preference to be 6.4 x 5 for a one-time and 6.3 x 4.8 long term. The study used 3D printed models to allow volunteers to choose their preferred size. While the results are interesting there appears to be some issues with the sample group: sexual orientation doesn't fit well with general population, many volunteers hadn't engaged in intercourse... The part that annoys me is they refer to the average penis size in many figures as 6 x 5 without a citation while the text refers to previous studies reporting between and average closer to 5.5 x 4.8. It is a minor issue but important in comparing the women's preference to the average size. Could also help describe why 21% of their participants reported ending a relationship due to a small pens. Here is the study:
